I cleaned out all of my gas cans today, got rid of a few that were beyond fixing, and I have about 2-3 gallons of gas that were in various cans. They weren't stored with Sta-bil, as it was before I learned about this wonderful product. Is there any way to rejuvenate this gas or should I just plan on starting a big bonfire with it? Or, is there anywhere to take old gas for safe disposal? If there is a way to make it useable again, that would appeal to my frugal and thrifty nature.
